i=sqrt(-1);
Rayleigh=1;
AWGN=0;???????????????????????????? % for AWGN channel
MMSE=0;???????????????????????????? % estimation technique
Nsc=64;???????????????????????????? % Number of subcarriers
Ng=16;????????????????????????????? % Cyclic prefix length
SNR_dB=[0 5 10 15 20 25 30 35 40];? % Signal to noise ratio
Mt=2;?????????????????????????????? % Number of Tx antennas
Mr=2;?????????????????????????????? % Number of Rx antennas
pilots=[1:Nsc/Ng:Nsc];????????????? % pilot subcarriers
DS=5;????????????????????????????? % Delay spread of channel
iteration_max=200;
非常好我支持^.^
(1) 100%
不好我反對
